The new GNOME 3 user experience requires a video card capable of 3D acceleration. Fedora 15 supports the widest possible range of these cards through free software drivers, including the ''nouveau'' driver for NVidia graphics cards, the ''radeon'' driver for AMD graphics cards, and the ''intel'' driver for Intel graphics cards. In situations where properly supported 3D acceleration is not detected, GNOME 3 offers a fallback mode that models the GNOME Shell behavior. 3D support in Nouveau is now available by default, and the ''mesa-dri-drivers-experimental'' package no longer needs to be installed.

+

−

+

−

==== How do I find applications? ====

+

−

+

−

Go to the top left corner to activate the hotspot and then click on ''Applications''. Alternatively, click on the ''Super'' key (also known as the ''Windows'' key) or Alt+F1, and start typing the name of the application or a related term.

+

−

+

−

==== How do I change settings? ====

+

−

+

−

Click on the user menu at the top right and select ''System Settings''. For more advanced preferences, install the ''gnome-tweak-tool'' package.

+

−

+

−

==== How do I shutdown/power off or restart the system? ====

+

−

+

−

Hold down the ''Alt'' key and click on the user menu. The ''Suspend'' menu item at the end of the menu will change into ''Power Off...''. While holding down the ''Alt'' key, click on that item. You will get options to shutdown or restart the system .

+

−

+

−

==== How do I change the behavior on laptop lid close? ====

+

−

+

−

The default behavior when a laptop lid closes is for the system to suspend. This default can be changed (and made different depending whether the system is running on battery or mains power, if desired).

+

−

+

−

Use '''gnome-tweak-tool''' or use either or both of the following commands:

Owen Taylor from Red Hat, one of the primary developers of GNOME Shell, explains the rationale [https://mail.gnome.org/archives/gnome-shell-list/2011-February/msg00192.html here] for removing these buttons by default. Minimize and maximize are still [http://blogs.gnome.org/diegoe/2011/03/05/minimize-and-maximize-in-gnome3/ available] on the context menu if you right click on the window title or hit ''Alt+Space''. You can also maximize by double clicking on the window title, or dragging the window over the top edge of the desktop. If you want to configure button appearance, use ''gnome-tweak-tool''.

+

−

+

−

==== Is there any way to tile windows? ====

+

−

+

−

You can tile windows by dragging them against the left or right side of the desktop. The window is automatically sized to take up that half of your desktop.

+

−

+

−

==== How do I make the panel display the full date/time? ====

+

−

+

−

Use '''gnome-tweak-tool''' or use either or both of the following commands:

+

−

+

−

* {{command|gsettings set org.gnome.shell.clock show-date true}}

+

−

* {{command|gsettings set org.gnome.shell.clock show-seconds true}}

+

−

+

−

==== What happened to applets? ====

+

−

+

−

Traditional GNOME panel applets are not supported in gnome-shell as explained [https://mail.gnome.org/archives/desktop-devel-list/2009-April/msg00267.html here]. The general design of GNOME 3 puts more emphasis on full applications, instead of squeezing too much into a small strip or space at the edge of your screen. There are, however, people working on an extension mechanism for the shell, similar to Firefox extensions. The code lives in [http://git.gnome.org/browse/gnome-shell-extensions this git repository]. We don't expect this to be available in polished or packaged form for GNOME 3.0, though.

+

−

+

−

Any existing applets that have been adapted to use the new ''libpanel-applet'' will be available in ''fallback'' mode. However, ''fallback'' is not considered the default mode of operation and will not be actively developed in the future. For more information on applets and transitioning to gnome-shell, see [http://live.gnome.org/GnomeShell/AppletsTransition this GNOME wiki page].

+

−

+

−

Some applets support a ''-w'' switch that allows them to run in a dedicated window if needed.

+

−

+

−

==== How do I start more than one instance of the same application? ====

+

−

+

−

Right click on the icon in the dash bar on the left side and click on "new window". You can do the same action from the applications window. Also several applications themselves offer a option to open a new window within the file menu.

+

−

+

−

==== How is multi-monitor support? ====

+

−

+

−

Great! Refer to [http://blogs.gnome.org/alexl/2011/03/22/multimonitor-support-in-gnome-shell/ this blog post] for more details.

+

−

+

−

==== What about themes? ====

+

−

+

−

GNOME Shell does not support theming by default. There are extensions that support themes via CSS, however. Themes can be changed system-wide or per user. As an example, a reference for a theme is provided below and instructions on using them:

+

−

+

−

* http://gnome-shell.deviantart.com/gallery/28081982#/d36szax

+

−

+

−

Advanced users:

+

−

+

−

For system-wide theme changes, you can use [https://github.com/sardemff7/GS-Theme-Selector this third-party tool]. For per-user changes, a GNOME Shell extension is [http://gitorious.org/gnome-shell-extensions available]. If the extension is installed, you can use ''gnome-tweak-tool'' to change the themes.

+

−

+

−

==== What about hardware/drivers without acceleration support? ====

+

−

+

−

For such users, GNOME offers a fallback mode that uses updated versions of Metacity and GNOME Panel, and works without any hardware acceleration. Fallback mode is automatically activated if GNOME Shell cannot be started. Note that fallback mode is not the same user experience as GNOME 2.x. It follows the user experience of GNOME Shell as much as possible. Adam Jackson from Red Hat has been [http://lists.fedoraproject.org/pipermail/test/2011-March/097795.html working] on making GNOME Shell work just using software acceleration and made some progress already.

+

−

+

−

==== Does GNOME Shell work under a virtual machine? ====

+

−

+

−

If your virtualization solution supports hardware acceleration, then yes. Otherwise it would automatically use fallback mode.

+

−

+

−

==== How can I force fallback mode? ====

+

−

+

−

Click on the user menu on the top right, Select ''System Settings'' -> ''System Info'' -> ''Graphics'' and toggle the ''Forced Fallback Mode'' switch to on.

+

−

+

−

==== What happened to the Fedora 14-vintage GNOME shell design? ====

+

−

+

−

It was an experiment that was part of the iterative design and learning process leading to the final GNOME 3 design. The code has developed beyond that design to make the GNOME Shell more usable.

+

−

+

−

==== Where is the desktop? ====

+

−

+

−

The desktop workspace no longer displays the contents of the user's ''~/Desktop'' directory. That directory and its content are still accessible through the Files application. To access the Files application, move your mouse to the Activities hotspot, use the ''Super'' key, or use the ''Alt+F1'' key combination to see the overview. Then type "files" or select the ''Application'' menu and choose Files. You can attach the Files application to your dash, the set of favorite applications on the left side, if desired.

+

−

+

−

==== How I start programs automatically when logging in? ====

+

−

+

−

Use ''gnome-session-properties'' to configure programs to start automatically. You can also create a desktop file or copy one from ''/usr/share/applications'' to ''~/.config/autostart'' in your home directory.

The Shell includes a built in screencast recording function. To activate recording, hit ''Ctrl+Alt+Shift+R'' and a recording icon appears at the lower right hand corner of the screen. To finish recording, hit ''Ctrl+Alt+Shift+R'' again. By default screencasts are recorded in a file named ''shell-YYYYMMDD-N.webm'', where YYYYMMDD represents today's date and N is incremented for each additional screencast.

+

=== GSettings and dconf ===

+

−

GConf is a legacy system for storing application preferences used in previous versions of GNOME. It has been replaced by GSettings in GNOME 3.0, and many core programs have already migrated. Fedora 14 was the first Fedora release to include GSettings. GSettings supports multiple backends, and the default in Fedora 15 is [https://live.gnome.org/dconf dconf]. The ''gsettings'' command line utility is the equivalent of ''gconftool-2'' in previous releases, although ''gsettings'' is more functional since it supports automatic completion of schemas and keys at the command line. The ''dconf-editor'' provides a graphical editor for managing settings similar to ''gconf-editor'' in previous releases.

=== GTK+ 3.0 ===

+

−

+

−

GTK+ 3.0 is also part of Fedora 15, which features numerous enhancements for application developers. Changes in the toolkit include:

+

−

+

−

* Modernized handling of input devices

+

−

* Improved and simplified drawing through Cairo rather than wrappers around old X11 methods

+

−

* A new theming API with a familiar CSS syntax

+

−

* Early stages of easier application support, such as window tracking and ensuring uniqueness

* Activities are easier to use. An [http://docs.kde.org/stable/en/kdebase-workspace/plasma-desktop/zooming-user-interface.html activity] is a number of different applications that open and close at the same time. In Fedora 15 with KDE 4.6, you can add an application to an activity by right-clicking on the window title. You can also manage activities by clicking on the ''Plasma Toolbox'' in the top-right corner of your desktop.

+

−

* The "Power Management" panel in '''System Settings''' is easier to use. The power management program has been rewritten so that it is faster and has fewer bugs.

* You can "pin" open applications to the '''Task Manager'''. When you close "pinned" applications, the '''Task Manager''' will still show them.

+

−

* The ''Plasma Netbook'' interface works better with touch-screen monitors.

+

−

+

−

=== Applications ===

+

−

* '''Dolphin''' offers a search bar and "filter" sidebar. Now you can easily search your files with ''Nepomuk'' and "Semantic Desktop" tags.

+

−

* '''Kate''' is available in the ''kdesdk'' package. There are many new plugins for Fedora 15:

+

−

** ''GDB'' (GNU Debugger)

+

−

** Add scripts to the menu

+

−

** SQL database connection

+

−

** Recover unsaved data if '''Kate''' crashes

+

−

* '''Gwenview''', '''KSnapshot''', and other graphics applications can export photos directly to social networking websites like Facebook and Flickr.

+

−

+

−

=== Platform ===

+

−

* The platform relies less on other software, so it uses less memory. This is useful for low-power computers like netbooks and smartphones.

+

−

* Users can backup the ''Nepomuk'' library. ''Nepomuk'' is the file indexing and search utility.

+

−

* ''UPower'', ''UDev'', and ''UDisks'' are used instead of ''HAL''. This change does not affect users now, but there will be more features in future releases.

+

−

* You can use the new ''Oxygen-GTK'' theme for GTK+ applications. KDE-designed and GNOME-designed applications will look the same when you log into KDE.

+

== Sugar ==

+

−

+

−

Sugar has been updated to the latest version 0.92 in Fedora 15. This

+

−

version provides major usability improvements for the first login

+

−

screen and the control panel, as well as new features such as support

+

−

for 3G networks.

+

−

+

−

==Xfce==

+

−

+

−

Fedora 15 sees the introduction of Xfce 4.8. This new release remains true to Xfce's goal of providing a fast, lightweight yet user-friendly desktop environment, while adding a range of new features and incremental improvements:

+

−

+

−

* '''Remote share browsing''': Thunar, Xfce's file manager, now has support for GVFS, allowing easy remote access to files and folders on Windows shares and FTP, Webdav and SSH servers;

* '''New Panel plugins''' such as '''window buttons''', which merges the features of the icon box and the tasklist into a single configurable plugin, and '''directory menu''', allowing quick browsing of a folder's tree structure;

+

−

* '''Easy application menu editing''' with any Freedesktop-compliant menu editor, such as Alacarte;
